Welcome
Hello, Azis syahrul anas, and welcome to Wikipedia! Thank you for your contributions.

I notice that one of the first articles you created appears to be an article about yourself. This is a common mistake made by new Wikipedians—as this is an encyclopedia, we wouldn't expect to have an article about every contributor. Your user page, however, is a great place to write about yourself, making sure to stay within user page guidelines. Just click your user name at the top of the screen when you are logged in, and edit it normally.

The page you created about yourself has been or will shortly be speedily deleted from Wikipedia, but if you want to use the content from it, don't hesitate to ask anyone from this list and they will copy it to your user page.

If you are stuck, and looking for help, please come to the New contributors' help page, where experienced Wikipedians can answer any queries you have! Or, you can just type   on your user page, and someone will show up shortly to answer your questions. Here are a few other good links for newcomers: I hope you enjoy editing here and being a Wikipedian! Please sign your name on talk pages using four tildes ( ~ ); this will automatically produce your name and the date. If you have any questions, check out Where to ask a question or ask me on my talk page. Again, welcome! Shirt58 (talk) 03:33, 21 April 2012 (UTC)

MENGACA
--Azis syahrul anas 04:44, 30 May 2012 (UTC)

Mengaca selalu dilakukan manusia. Ada sinar pantul penyebabnya.

Cermin digunakan untuk menampakkan bayangan dalam berkaca tentulah harus memiliki sifat dapat memantulkan secara merata sesuai bendanya.

Bayangan dihasilkan:

a. tegak b. semu

Pelapis di sebaliknya dikelupas berwarna keperak-perakan dinamakan perak-amalgam.

Bayangan  sebuah,  sebab dianggap mengaca bersudut 180o.

Jika digabungkan 2 buah  sehingga membentuk sudut tertentu, bayangannya  sesuai rumus :

360o n = ( -- )- 1 α

α adalah sudut  dibentuknya, n adalah jumlah bayangan dibentuk. Misalkan sebuah penghapus pensil diletakkan di depan bersudut 120o, bayangan dibentuk adalah 2 buah.

--Azis syahrul anas 04:59, 22 April 2012 (UTC)== BAYANGAN ==

Sebuah pensil diletakkan di depan kaca lipat. Apabila sudut diatur     60o, berapakah jumlah bayangan ?

Penyelesaian :

Diketahui : α = 60o

Ditanya   : n ?

Jawab :

360o n = (  -  ) - 1 α

360o = (  -  ) - 1                                       60o

=  6 - 1 = 5

--Azis syahrul anas 06:28, 22 April 2012 (UTC)== HURUF LAMDA ==

Rumus untuk λ  (  lamda ) adalah :

s                      λ  =  - n

λ = panjangnya gelombangnya satuannya m ( meter )

s = jarak gelombangnya satuannya m ( meter )

n = jumlah gelombangnya

Belum ada penulis rumusnya. Bagus dalam mengkaji rumus - rumus lain.

Rumus tersebut dapat dikembangkan lebih lanjut. Misalkan sebagai berikut ;

Gelombangnya merambat  6 m  membentuk 30 buah jumlahnya. Berapakah panjangnya gelombangnya ?

Penyelesaian :

Diketahui :  s = 6 m                              n = 30

Ditanyakan : λ ?

s       6 m                jawab      :  λ = -  =  -- = 0,2 m                                    n        30

CARA MEMBUAT MODEL CERMIN DATAR DARI PLASTIK MIKA
Karya : Azis Syahrul

--Azis syahrul anas 08:33, 29 May 2012 (UTC)

Bahan utama tentu saja plastik mika yang bening yang tidak berwarna. Sebab banyak variasi warna yang tersedia.

Alat ini digunakan untuk memberikan penjelasan mengenai sifat-sifat yang dihasilkan oleh bayangan cermin datar. Penggunaan dari alat ini tidak sulit. Ada 2 jenis model alat ini, yaitu : 1. model yang dapat dilipat 2. model tunggal

Kedua model ini asli karya penulis. Sebelumnya tidak ada/belum pernah ada yang membuatnya. Karena karya ini tercetus dari pemikiran penulis yang keseharian berprofesi sebagai guru di sekolah. Meskipun alat ini tergolong sederhana dan hanya dengan biaya sekitar Rp 20.000 - Rp 25.000, alat ini mudah dibuatnya dan mudah menggunakannya.

Penggunaan plastik mika ini sebagai inovasi dalam pembelajaran IPA yang berkaitan dengan cahaya dan pemantulannya. Meskipun tidak sepenuhnya dapat menggantikan peran cermin, tetapi kemudahannya dapat menjadi alternatif dalam mengakali media pembelajaran yang merupakan sarana dalam menunjang pembelajaran yang kreatif dan inovatif di kelas.

Guru diharapkan dapat selalu membangun citra profesional dan seorang pengabdi pengetahuan bagi tunas-tunas bangsa di masa sekarang dan di masa yang akan datang. Pembangunan citra ini harus selalu terpupuk melalui karya-karya yang kreatif dan inovatif, sehingga menarik minat siswa untuk belajar dan terus mengasah kemampuannya. Sesuai dengan memajukan kesejahteraan umum melalui budaya mencerdaskan bangsa di tingkat sekolah.

Banyak hal yang bisa didapatkan di dalam penerapan alat ini. Siswa mampu memahami setiap perkembangan ilmu pengetahuan. Seyogyanya kecintaan belajar perlu selalu disemangatkan oleh guru, agar mereka mau menimba ilmu tidak setengah-setengah.

Model yang dapat dilipat

Plastik mika dipotong menjadi 2, kemudian diberi bingkai masing-masing dengan styrofoam yang berukuran sama dengan plastik mika. Untuk menempelkan plastik mika ke styrofoam menggunakan doubletif. Untuk membuat engsel pada kedua styrofoam menggunakan kertas karton yang ditekuk dua sesuai panjang dan lebar sisi styrofoam yang disatukan. Untuk lebih bagus penampilan plastik mika, sisi-sisinya dibingkai dengan kertas karton, sehingga tampak seperti bingkai foto di rumah. Bagian pendukung alat ini yang tidak kalah penting adalah styrofoam untuk menentukan sudut-sudut bagi penempatan benda yang akan dilihat bayangannya. Untuk menggambar sudut-sudut 0, 30, 36, 40, 45, 60, 72, 90, 120 dan 180 derajat dari kiri ke kanan digunakan kertas karton, penggaris, busur derajat dan spidol kecil berwarna hitam. Untuk pencahayaan dapat menggunakan nyala api lilin atau cahaya dari lampu pijar kecil. Untuk lampu pijar ini menggunakan kabel dan dua buah baterai.

Model yang tidak dapat dilipat / model tunggal

Cukup menggunakan 1 plastik mika bening yang utuh. Kemudian bingkai sisi-sisinya saja, sehingga plastik mika tembus pandang. Untuk pencahayaan sama dengan yang digunakan oleh model yang dapat dilipat.
